Note, some of our tools require the lower case letters to be replaced with upper case letters before you can import pronto hex._________________Remember to provide feedback to let us know how the problem was solved and share your upgrades.

Tip: When creating an upgrade, always include ALL functions from the oem remote, even if you never plan on assigning them to a button. Complete function lists makes an upgrade more helpful to others.

The HTX series use ordinary Onkyo codes but for remote ID 3. One way to proceed is to use an Onkyo spreadsheet (e.g. TXNR1009 - IR), and decode the Pronto Hex shown in the 3rd Pronto Hex column (usually Column E) of the spreadsheet.

Actually you probably don't need to decode. Instead use the information in column A, which is device.subdevice and function number expressed in hexadecimal format. For example Discrete Power On is shown as D26D 04, which we recognize as device 210, subdevice 109, function (OBC) 4. ID 3 codes use the same 210 device, and OBC values, but use different subdevice numbers.

Pronto Hex can be decoded with several programs, but I recommend either IrMaster (Java) or IRScope (Windows only). In this particular case, where we want to see patterns in the decodes, IRScope's table display is more convenient. I simply tried a number of the Pronto Hex signals, and it's easy to see the substitutions. See also this thread by madmalkav, where he says that ID3 matches HTX codes.

The Decode of the ID 3 Pronto Hex corresponding to D21E 50 0F is givien as NEC1-f16 210.30 OBC 82 OBC2 15. This isn't the best display of the info, but DecodeIR was designed a long time ago, and it is hard to change now. Anyway, you can see that in this case, the 3rd number is different, and trying a few others shows that consistently 80 is replaced with 82 for ID 3.

We have a executor for this situation called NEC1-f16 3Fixed. Use it but change Device3 from the default 80 to 82. Use OBC2 from the decode in the OBC column on the functions tab.

You'll probably be using NEC Combo (Official) for most of the Onkyo functions, so if you want to keep these on the same device key, you'll probably need to use two upgrades, and use keymoves to access these NEC1-f16 signals. We sometimes refer to this as a helper upgrade.

I just bought an HTX-22HDX, and was a little disappointed to see that discrete codes for input selection and power weren't available. It's excellent to see this thread, and I will try to add the codes myself, but I wondered if anybody had had any success?

If Harmony's database doesn't have the codes, ask them to put them in.
You have all the information they need from the post in this forum.

If you need the code immediately you can set up some UEI remote to teach your Harmony. You might have one and not know it.

The Atlas line of remotes (big ugly 5 device remotes with a big bulge in the top that it looks like it swallowed a yo-yo) or a RCA RCRP05B remote that you can usually pick up for under $20 at various retailers can do the trick for you.

There are many other UEI remotes that you may already own that can do the trick too. If you have any remotes with a 6 pin connector in the battery compartment you have one of our remotes.
